Case Study丨How to Boost Cell Phone Signal in Multi-Story Residential Building

In some countries and regions, multi-story residential buildings are constructed using large amounts of reinforced concrete, leading to significant attenuation of cell phone signals and affecting usability. Particularly with advancements in mobile technology from 2G and 3G to the era of 4G and 5G signals, reliance on mobile communication has increased along with the rise in data transmission. However, with each generation of mobile communication technology advancement, the ability of signals to penetrate has noticeably decreased in the face of exponentially increasing data transfer rates.

Faced with weaker 4G and 5G signals in multi-story residential buildings, how can cell phone signals be boosted? Up to now, I have searched various DIY methods online to boost indoor cell phone signals in buildings, but the results have been minimal. Therefore, the only effective method to booster indoor cell phone signals in buildings is to purchase and install a professional cell phone signal booster.

 

Recently, Lintratek received a project request to enhance cell phone signal in a 4-story residential building. The homeowner indicated that the signal is good only on the 4th floor, progressively weakening on the 3rd and 2nd floors, where connectivity is limited to phone calls on the 2nd floor and accessing the internet is difficult. By the 1st floor, there is no cell phone signal reception at all, creating a signal dead zone. Additionally, due to the weak signal on the 2nd and 3rd floors, phones actually consume more battery compared to the 4th floor where signal strength is better.

 

Therefore, the homeowner seeks Lintratek’s products in boosting the cell phone signal inside their building to resolve the signal dead zone issue.

Following on-site surveys and internal discussions by Lintratek’s technical team, we have decided to recommend the use of Lintratek’s KW27B cell phone signal amplifier host for their cell phone signal booster system. This system is well-suited for multi-story residential buildings, offering excellent adaptability, durability, and energy efficiency, effectively addressing signal dead zones in such environments.

Installing Outdoor Antenna:

Considering the building layout and client preferences, signal coverage is targeted for floors 1 to 4. The outdoor antenna will be mounted on the rooftop of the 4th floor, and the feeder cable will be routed to the signal amplifier main unit on the 2nd floor.

Installing Coverage Antennas:

On the 1st floor, install 4 ceiling antennas across 4 rooms. On the 2nd floor, install 2 ceiling antennas in rooms where the signal is particularly weak to enhance coverage.

Signal Testing:

Use software to measure signal values across the floors, ensuring that the RSRP (Reference Signal Received Power) values for cell phone signals fluctuate between -86dBm to -100dBm. This ensures smooth calling and internet browsing. (RSRP values measure signal smoothness; values above -80dBm indicate excellent performance, while below -110dBm suggest poor connectivity.)
